Essendon will decide in the next few days whether to continue David Zaharakis' return in the VFL this weekend, or prepare him for round two with a challenging week of training.

Zaharakis returned from a quad injury to the senior side against Adelaide on Friday night and played a little over a quarter. The Bombers have a week off before playing Melbourne.

The onballer said on Sunday that he expected to play more minutes for the stand-alone Essendon team's first VFL game on Friday, but general manager of football Danny Corcoran said a call was yet to be made and Zaharakis was more likely to keep training.

''He might play in the VFL. It's a possibility, but we'd have to get permission from the AFL for him to do that, I would imagine,'' Corcoran said.

''But we haven't had a match committee meeting yet and we might decide it's better for him to just keep training.''

Zaharakis, speaking on Channel Seven's Game Day, said coach James Hird had addressed the emotional impact of the Australian Sports Anti-Doping Authority and AFL investigation into the club leading into the Adelaide match.

''We didn't shy away from it. Hirdy spoke about the last six weeks and the ordeal of it all,'' he said. ''It takes its toll on everyone and it's ridiculous people can start targeting your family or your kids.''

Former Essendon player Mark McVeigh, appearing on the same show, said he and the other players had the club's supplement program explained to them in a PowerPoint presentation at the start of the 2012 pre-season, and that none of them would have taken anything they thought to be against the rules.

''The club has got their own investigation, we have to respect that,'' he said.

''I'm looking forward to seeing what comes out of that. There is some concern around that and the way certain people may have got into our club that may have had a dodgy past or history, but … I commend Essendon for having this investigation internally.''
